# SQL Server, Query Store object

 [!INCLUDE [SQL Server 2016](../../includes/applies-to-version/sqlserver2016.md)]

The Query Store object provides counters to monitor resource utilization of [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)] to store query texts, execution plans, and runtime stats for objects such as stored procedures, ad hoc and prepared [!INCLUDE[tsql](../../includes/tsql-md.md)] statements, and triggers.  
  
This table describes are the **SQLServer:Query Store** counters.  
  
|SQL Server Query Store counters|Description|  
|-------------------------------------|-----------------|  
|**Query Store CPU usage**|Indicates Query Store's usage of the CPU as a percentile of the use of the CPU by other processes.|  
|**Query Store logical reads**|Indicates the number of logical reads made by the Query Store.|  
|**Query Store logical writes**|Indicates how much data is being queued to be flushed from the Query Store. The frequency and delay of adding items (that represent runtime stats) to the queue is controlled by Data Flush Interval setting.|  
|**Query Store physical reads**|Indicates the number of physical reads made by the Query Store.|  
  
 Each counter in the object contains the following instances:  
  
|Query Store instance|Description|  
|--------------------------|-----------------|  
|**_Total**|Information for the Query Store for this instance of [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)].|  
|\<database name>|Query Store information for this database.|  

  
## Example

You begin to explore the query performance counters in this object using this T-SQL query on the [sys.dm_os_performance_counters](../system-dynamic-management-views/sys-dm-os-performance-counters-transact-sql.md) dynamic management view:

```sql
SELECT * FROM sys.dm_os_performance_counters
WHERE object_name LIKE '%Query Store%';
```
